847	users.create_user fails if User is subclassed using replaces_module = 'auth.users'	EABinGA	Adrian Holovaty	"Given the following model:


{{{
class User(auth.User):
    class META:
        admin = meta.Admin()
        replaces_module = 'auth.users' 

    foo = meta.URLField(blank=True)
}}}

¨django-admin.py sql auth¨ creates the correct output


{{{
CREATE TABLE ""auth_users"" (
    ""id"" integer NOT NULL PRIMARY KEY,
    ""date_joined"" datetime NOT NULL,
    ""last_login"" datetime NOT NULL,
    ""is_superuser"" bool NOT NULL,
    ""is_active"" bool NOT NULL,
    ""is_staff"" bool NOT NULL,
    ""password_md5"" varchar(32) NOT NULL,
    ""email"" varchar(75) NOT NULL,
    ""last_name"" varchar(30) NOT NULL,
    ""first_name"" varchar(30) NOT NULL,
    ""username"" varchar(30) NOT NULL UNIQUE,
    ""foo"" varchar(200) NOT NULL
);
}}}

But an attempt to create a superuser with django-admin fails.
A debugging session yields the following:
